By Chelsea J. Carter and Masoud Popalzai

A man in an Afghan military uniform killed three U.S. troops Friday in southern Afghanistan, a day after the United States condemned a suicide bomb attack that left four Americans dead.

The man opened fire on the troops in the volatile Helmand province, said Maj. Lori Hodge, a spokeswoman for the International Assistance Security Force.

Hodge did not immediately provide details about the attack, one of a handful of attacks in recent weeks to target NATO troops.
